6 speed tt

[SVTCobra60]

If im building a car that will see the track a lot and I mean a lot, I would throw a TH400 in the car without thinking twice. But for someone like me, a car that see's more street use than track and not abusing the crap out of it, the 4r would be my choice. aj's car with the 4r is nasty. He still wants me to go for a ride in it but I refuse to go inside. On 12-14lbs that car is scary. Maybe next time I see him at mustang magic ill go for a ride, but I will tell him to put it on very low boost just to feel.

I have been in joeys mustang. mustang magics tuner. He has a twin turbo setup in his mustang 4v swap with a 4r. He rolls around on 10-12lbs on the street and says he barely uses the high boost button lol. lays waste with 10lbs

I'd love to take rides in these cars! I'm right near mustang magic too lol. Never have seen any of them around.

I have been in all the heavy hitter car's they built. From venomous johns car to snakebite. Now that I am older I think twice about getting in those car's. The twin turbo mach 1 and the twin turbo cobra they built are just stupid fast.

I dont have twins but Im going auto as soon as the funds allow. Im wondering how much out of pocket itll cost to go th400 after i sell all the t56 stuff.

I'd also like to know this! Hopefully someone who did it can give you numbers.

Lucky you! What kind of power are these cars making?

the tt mach1 just got back on the road and still has baby 57mm turbo's so im not sure on the numbers. and this is aj's car MustangJunkies.net AJ Twin Turbo Cobra Dyno - YouTube

Turbo's are driven by exhaust gases. The 3.27's will put more load on the engine for a longer amount of time than 3.73's, therefore creating more exhaust gases to drive the impeller.

But if I ran 3.27's... My crusing rpm would be to low in 6th gear.
And I'm running more compression so my turbo spools up no problem.

 

[TwinTurbo4vGT]

Why would you want to be cruising in 6th anyway???

 

[fangs99]

Well I can't make a 4th gear pull all the way from P'cola to Tampa.... My car is a driver... Not a trailer or garage queen.

Indeed we do...have Matt set it up. :beer:

After selling my T56 stuff out of pocket was like $2500-$3000 for my Th400 swap. Total was around $5000

So what? You want your cruising RPM to be low in 6th gear. Yes your turbo spools quick with the higher compression, but the 3.27s would help load it up and spool quicker plus have a MUCH more useable powerband, better traction etc etc.

Thanks for the isnight on the price thats about what I was figuring price wise.


And your right about the gearing, spooling is half the battle, turbo cars do better when they can stay in boost, thats whats great about the powerband of a turbo car, its making its power consistently from say 4k-6500, you dont want it to rev out quickly to its peak like N/A or blower cars.

 

[fangs99]

My car spends plenty of time in it's power band... 3,500-7,000.... I do want my rpms low when cruising, but not to where it's laggy and I have to down shift for every hill on the hwy...... Besides when I go up to a 28 inch tire... It will be equal to some where between a 3.55 and 3.31.

 

[AntiHeightPunk]

I have 3:27's and a 28 inch tall tire shit rides out in boost i might do even less gear if it exists

 

[fangs99]

You can.... There's 3.15, 3.08 and 2.73 as an option.

 

[SVTCobra60]

I'd like to bring this back to the top and get more insight on what people think of 6 speed TT cars

 

[AntiHeightPunk]

not as fast as th400 cars

 

[1MIXDUP]

Hey when are you coming out bro :beer:

 

[AntiHeightPunk]

ill come out whenever....i don't street race much anymore. Too old

 

[SVTCobra60]

not as fast as th400 cars

I don't doubt that, but are they street-able and useful? Lol. I would love to go TH400 for my future car. But I'm most likely gonna have a 6 speed in it at first. Just want to make sure it doesn't suck ass.
